t will be understood that the valve 8 should be an ordinary'check valve or inlet valve so that it will cut off the back pressure by which arrangement the gas is compressed in the intake chamber and when the piston is moved downward to a point below the top of the intake port 13, the gas in the intake chamber is released and finds its way into the piston cylinder 1. For the pur ose of preventing the new charge of gas .sion, the deflecting. plate 14 is provi ed, which deflecting plate is secured to the piston 3 in any convenient and well known manner.

Itwili be understood that the gas should be confined in the crank and compression chamber during the downward stroke of the piston except asreleased for a new charge through the passages 10'and 11 and the port power shaft is provided with the rings 17,

It will of course he understood that the piston cylinder is to be Water cooled in the usual manner by a circulation of water by means of the inlet pipe 20 and the outlet pipe 21. Ihave discovered by actual use that during the time the engine is running slowly it is difficult to supply a sufficient amount of gas, but by providing the large intake charm her 6 and the horizontal'and vertical passages 10 and 11 this diflicrdty is entirely overcome, owing to the fact that the intake chamber can be instantly recharged the instant the piston starts on its downward movement as t intovthelintakeqhal iiber and the passages can therebycompletely filling the crank andcomntake'chamber andthence into the piston vertical passages 3' and into the intake- I It will be understood that-the exhaust port- 15 is to be provided and is of the usual con-' 13, and in order to prevent any leakage the' thereis both horizontal and vertical passage be formed of such a size that the gas'is free'toass from the compressionchamberinto the during the time the piston moves downward,
